AMD plans to do a little refresh of its desktop A-series Llano APUs that will include three new APUs, the A8-3820, A6-3620 and the A4-3420. As you could have guessed from the names, we are talking about two quads and one dual-core APU that will replaced the A8-3800, A6-3600 and the A4-3400.

The new APUs are pretty much the same as the ones that they are meant to replace but with a slightly higher clock. The A8-3820 will be clocked at 2.5GHz with a 2.8GHz Turbo and will have the same HD 6550D GPU part. The A6-3620 ticks at 2.2GHz with a 2.5GHz Turbo and has the same HD 6530D GPU part, while the A4-3420 works at 2.8GHz and has the same HD 6530D GPU part. All three new parts have the 65W TDP, same as their predecessors.

The A8-3800, A6-3600 and the A4-3400 will coexist with the new ones until the end of Q2 2012. After Q2 2012, AMD won't be having any more orders for these. Of course, we expect the mentioned trio to have a slight price drop as soon as the refresh shows up in the market.

It is also important to know that Q1 2012 is the launch timeframe of the A6-3670K, while the A8-3870K is scheduled to ship in Q4 2011.

A quick glance of our favourite European price search engine revealed early listings of AMD's desktop Llano APUs, the quad-core A6-3650 and A8-3850.

In case you missed it, the A6-3650 is a 2.6GHz part with 4MB of L2 cache and an HD 6530D graphics core with 320 shaders and a 443MHz clock. It has a 100W TDP and was earlier listed in the USA for US $126. The European listing that we found puts it at €109,25.

The next one is the 2.9GHz flagship A8-3850 APU featuring an HD 6550D graphics part with 400 shaders and 600MHz clock. This one has the same 100W TDP and supports dual-channel DDR3-1866 memory. It was previously listed in the USA for around US $150 and has now showed up in Europe with an early listing at €129,29.

Of course, bear in mind that these are, as noted, early listings and that price might be a bit different once these are officially announced. We still don't have a precise date for the desktop Llano launch but we'll get back to you with this pretty soon, as it might be just around the corner. Some retailers expect to see desktop Llanos in stock in the first half of July.
